Preheat oven to 400 degrees. Place unwrapped brie round in brie baker or another oven proof dish. Score or remove skin from top of round. Place in oven for 8-10 minutes until it bubbles slightly. Remove and pour 4 tablespoon over top of brie. Add pecan pieces to top and run back in oven for another 5 minutes so Dr. Pete's Praline Mustard Glaze bubbles.
